(5) Open and secure condenser inlet and outlet panels.

(1) During warm or cold weather.
(a) Limit traffic through doors as much as possible.
(b) Keep doors and windows tightly closed.
(c) Limit use of fresh (outside) air.
NOTE
It is normally better to keep the fresh air damper slightly open. This will create a slight overpressure,
provide replacement oxygen, and reduce room odors. Damper should be closed during extrem weather
conditions and during periods when fast warmup or cooling is necessary.
(d). Do not adjust controls unnecessarily. Properly set the controls (See Paragraph 2-8 thru 2-11) and the
unit will automatically control the temperature. The temperature control thermostat on the control panel operates like a
conventional room thermostat except that the temperature scale is not marked on the control panel. The thermostat has a
control range of 40 F to 90F (5 to 32 C). The centered position of the control knob would be approximately 65F (18 C).
The full INCREASE would be 90F (32 C). The full DECREASE would be 40F (5 C):
(2) During cold weather. Adjust shales, blinds, etc. (when applicable) to admit sunlight during day. Close them at
night.
